Dorot Control Valves, along with other companies involved in this project, were sent in order to pump water to the villages and city.
For this project Dorot supplied Air valves, pumps, QR valves, water meters, pressure reducing valves, pressure sustain valves, differential and Modulating float controlled valves,
The project was divided into a number of sites:
- Pump sites
- Logistics site
- Mountain tanks
- Water lines
Pump Sites
Exit from the pumps (total 5), PR/PS, Series 300, diameter 8", which I calibrated to 90 m sustaining and 75 m reducing, after adding needle valves and another water source, adjustment Limit switches connected to the electrical panel of the pumps, warn on the valve open/closed.
5 QR valves, series 300, 3" angle, which I set, discharge pressure of 110 meters.
5 units air valves 2". 5 units water meter, Woltman 8".
The 6" surge anticipating valve series 100 was changed to QR and set to discharge pressure of 80 meters.
Logistic Site
4 units Differential Float Controlled Valve, series 100, 8", arrangement of command tubing, adjustment of the float to terraced heights, reversion one valve, enable electric closure from Amiad filters during washing.
I modified the 3W pressure reducing, series 100, 8", for water supply to containers on the mountain to a 2W pressure reducing. Woltman water meter 12", at the outlet of Amiad filters, needs to be converted output pulse 1:1000. Amiad want change the surge anticipating electric valve at the output of the filters, to a surge anticipating hydraulic valve.
Mountain Tanks
4 valves, Modulating Float Controlled, Series 500, diameter 4". Checked integrity of the system after replacement valves were installed by Yossi.
